Specification of Letters Patent.

Patented April 27, 1909.

Application filed June 4, 1908. Serial No. 436,736.

To all whom it may concern:

Be it khown that I, JASPER L. GREEN, cltizen of the United States, residing at Mas-- sillon, in the county of Stark and State of;

Ohio, have invented certain new and useful Improvements in Tipples,flof which the fol-' lowing is a specification.

This invention comprehends certain new, and useful lmprovements in t1 pies, and reper at the lower end of the screening chute,

in addition to Ysegregating the fine coal, slack, foreign matter or the like, the apparatus also providing means whereby the weight of said egg coal, for instance, thus separated,

dumped, if desired. And a further object of the invention is a simple, durable and effi cient construction of ap aratus of this character that is so arran ed that the entire load passing down the c ute may at will be shunted therefrom directly into an egg pocket or casing forming a subjacent compartment of the weighing'pan, instead of passing to the floor of the pan where the egg size would be separated from the larger lum s. i g v V V lith this and other objects in view that will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts thatl shall hereinafter fully de, scribe and claim. For a full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction, reference is to be had to the following descri tion and accompanying drawings, inwhi c Figure 1 is a top plan view of a tipple c 1 bodying the improvements of my invention;

Fig. 2 is a side elevation thereof ;v Fig. 3 is a longitudinal sectional view; and, Fig. 4 is a detail sectional view on an enlarged scale, of the means for locking the discharge door of the egg dum or pocket in a closed position.

Correspon 'ng and like parts are referred to in the followingdescription and. indicated of illustration only. here shown comprises uprights -1 connected at their upper ends to longitudinal sills 2,.

- sides of the pan in all the views of the drawings, by the same reference characters.

The framework of my improved apparatus may be of any desired construction or design,

such as is ordinary with tipples, and it is to be understood that the framework shown in the present instance is selected for purposes The present framework braces 3 connecting the sills to the uprights. 4 designates the ordinary chute which is formed with-a series of longitudinally extending laterally spaced bars 5 forming a screen which is suspended in an inclined position in any desired way, for instance, by being bolted at-its upper end to one pair of uprights 1 and being suspended at its lower end by means of a hanger 6.

The weighing pan 7 is suspended from the ,scales or'weighing apparatus, with one end close to and underneath the lower end of the may be determined before the pan has been.

chute 4, hangers 8 and 9 being shown as the suspending means in the present instance, the hanger 8 being connected in any desired way to the frame or platform 10 of a weighing device which may be of any'desired type and which by itself forms no part of my in vention. Merely to show the operative structure, I have indicated that the platform or frame 10 is connected by link rods 11 to a scale beam 12 (see Fig. 2). The hanger 9 is connected to a chain or cable 13 which swings around a drum 14 carried by the scale platform or frame 10 and which thence extends around a sheave 15, the counterbal-.

2ancing weight 16 being secured to the free end of said cable, In order to control the tilting or dumping operation of the pan 7, I

= have shown in the present instance a brake band 17 which encircles the drum 14 and which is provided with a weighted operating handle 18-.

19 designates the end gate of the pan 7, said gate being pivotally connected to the y links 20, and being fconnected at its upper edge to a cable 21 which extends upwardly and is secured to the framework 10, for instance, sothat as the pan is dumped, the end gate will be raised so as to permit the coal resting upon the pan to slide therefrom into the car.

It is to be understood that all of the above named parts may be of any desired construction and type, as my invention is not comprehended therein, but in an attachment or pddition to thetipple, as hereinbefore set ort As has been before stated, my invention has for its object an attachment for the weighing pan 7, so that the egg or pea coal may be separated from the larger lumps. For this purpose, I provide the floor of the pan 7 with a screen 22 formed by a series of longitudinally extending and transversely spaced rods, as shown, and I secure to the pan, underneath said floor, a casing 23 which preferably extends the full width of the pan and to which the screen 22 leads. This casing 23 forms an egg dump or pocket, and it is provided with a bottom discharge opening controlled by a plate-like door 24;, said door being hinged at one edge as indicated at 25, and being made to swing dew-nwardly to permit the contents of the pocket to be discharged. In order to hold the door 24; closed, I have provided it with a latch bolt 26 which is encircled by a spring 26 exerting a tension upon said bolt so as to cause it to move into engagement with a keeper 27 secured to the front edge of the casing 23. The rear end of the latch bolt 26 is secured to a link 28, and said link is in turn pivotally connected to one arm of a bell crank 29 fulcrumed at its elbow on the arm 30 secured to and extending rearwardly from the door 24. A pin 31 is connected to the other and rearwardly extending arm of the bell crank 29 and passes freely upwardly through the end of the arm 30, and spring 32 encircles said pin and acts eXpansively upon the bell crank. 33 designates an operating handle for the door, said handle being secured at one end to the rearwardly extending arm of the bell crank and being suspended intermediate of its ends by a chain or cable 34 secured to a portion of the weighing pan, so that by pulling down upon the upper free end of the cable, the bell crank.w1ll first be rocked to retract the latch 36, and the continued usward'movement of the handle will swing t ie door downwardly, so as to permit the load' within the casing 23 to be discharged. In order to return the door to a closed position, it is connected at each end with a link 241E, the two links being connected at their upper ends with counterbalancing levers 24 fulcrumed on the sides of the weighing pan 7.

In order that the entire load of coal passing down the chute 4 may be shunted directly therefrom into the egg dump or casing 23 so as to prevent the separation of the egg coal from the larger lumps, when such separation is not desired, I provide the floor of the weighing pan 7 with a hinged section 35 located in advance of the screen 22 and lead ing into the casing 23. This hinged section issecured to a bail 36, said bail being in turn connected to a link rod '37 fastened to one arm of an operating lever By pulling downwardly upon the chain 39 or similar means secured to the opposite end of the operating lever 38, it is obvious that the hinged. section 35 may be raised so as to permit the coal to pass directly into the easing 23 as it leaves the chute 4, instead of passing on to the screen 22.

In the practical operation of my egg dump, the cars as they come from the mines are dumped onto the chute 4;, the coal passing down over the screen 5 for the usual screening operation. As the coal is thus passed onto the weighing pan 7, the smaller size coal, such as the grades known as egg or pea, will pass through the screen 22 into the subjacent egg dump 23. After this separation has been eii'ected, the smaller coal in the casing 23 may be dumped into a car underneath said casing, and the larger lumps are then discharged into another car by tilting or dumping the weighing pan 7 in the usual manner. Manifestly, if desired, the weight of the egg coal may be determined without the necessity of weighing it in the car into which it is discharged from the casing 23, by merely first determining the weight of the entire amount of coal in the pan, 7 and its subjacent pocket, then discharging the egg coal from the pocket and again weighing the coal remaining in the pan.

Having thus described the invention, what I claim is:

1. In an apparatus of the character described, the combination of a chute, a weighing pan suspended at the lower end of the chute, and formed in its bottom with a screen, a casing secured to the pan underneath the bottom thereof and in operative relation to the screen, said casing being formed with a. discharge opening and a door controlling said opening, the said bottom of the pan being provided with a movable section located between the screen and the chute, and means for raising said section so as to form an obstruction between the chute and the screen whereby the coal passing from the screen may be shunted directly into the casing and be prevented from passing upon the screen of the weighing pan.

2. In an apparatus of the character de scribed, the combination of a chute, a weighing pan suspended at the lower end of the chute and formed in its bottom with a screen, a casing secured to and forming part of the weighing pan underneath and in. o sierative relation to the screen, said casing being provided with a discharge opening and a hinged door controlling said opening, an arm projecting rearwardly from the door )ast the hinged edge thereof, a bell crank in crumed on said arm, a latch bolt carried by the door, the casing being formed with a keeper for said bolt, a link connecting said latch bolt with one arm of the bell crank, an operating handle connected to the other arm of said bell crank, and a support for said handle.

3. In an apparatus of the character described, the combination of a chute, a weighing pan suspended at the lower end of said chute and formed in its bottom with a screen, a casing secured to and forming part of the Weighing pan underneath and in operative relation to the screen, said casing being provided with a discharge opening, a hinged door controlling the opening, an arm projecting inwardly from the door past the hinged edge thereof, a bell crank fulcrumed on said arm, a latch bolt carried by the door, the casing being formed 'With a keeper for the bolt, a link connecting said latch bolt with one arm of the bell crank, an expansion spring encircling said bolt, a pin connected to the rearwardly extending arm of the bell crank, passing upwardly through said arm, aneXpansion spring encircling said pin and bearing against the bell crank and the first named arm, an operating handle connected to said last named arm of the bell crank, and a support for said handle.

In testimony whereof I affix my signature in presence of two Witnesses.
